Specification of Letters Patent.

Patented June 1914.

Application filed January 3, 1914. Serial No. $10,208.

'1 0 all whom, it may concern:

lie it known that 1, JOHN RUBBER" VVnA'rnnRsnY, a citizen of the United States, residing at Middlesex, in the county of Nash and State of North Carolina, have invented new and useful Improvements in Clevises, of which the following is a specification.

This invention relates to clevises for plows and similar farming implements.

One object of the invention is to produce a clevis of simple and improved construction which may be readily applied to a plow beam which will be held securely in position when applied and which will permit of vertical adjustment of the draft.

A further object of the invention is to produce a clevis of the character described which will permit of convenient detachment and replacementof the draft link.

l Vith these and other ends in view which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing, Figure l is a side elevation partly in section, showing the front end of a plow beam equipped with the improved clevis. Fig. 2 is a horizontal sectional view taken on the line 2-4 in Fig. 1. Fig. 3 is a perspective view showing the position occupied by the parts when the draft link is to be exchanged or adjusted.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved clevis includes in its construction top and bottom members 15, 16 which when combined and juxtaposed form a U-shaped member adapted to be mounted on the forward end of a plow beam 13. The top and bottom members may be described as consisting of plates or bars fitted upon the upper and lower faces of the plow beam and provided at their forward ends with arms or brackets 17, 18 which are provided with terminal overlapping lugs 19. The top and bottom members are provided near their rear ends with apertures 1st for the passage of a fastening pin or bolt 20. Said top and bottom members are also provided near their forward ends with keyhole slots 21 for the passage of a fastening belt or member 22. It is obvious that the plow beam is to be provided with apertures alining, respectively, with the apertures 14 and the keyhole slots 21 for the passage of the bolts or fastening members '20, 9.2. Said fastening 1nembers may be threaded at their lower ends for the reception of nuts or for engagement with the apertures in the bottom member 16 which may be correspondingly threaded, as seen at 23, although within the scope of the invention other well known means may be adopted for retaining said fastening members in position. The fastening members 20 and. 2-2 are, moreover, provided at their upper ends with beads 2 f constituting wrenches for general use.

i. draft plate 25 is provided, said draft plate being provided at its forward edge with foiwvardly extending pins 526 to engage apertures 27 in the arms or brackets 17, 18. The rear side of the draft plate is provided. with recesses 28 adapted to accommodate a draft iink 29, said draft link being confined in one of said recesses by engagement with the front end of the plow beam, as clearly seen in Fig. 1. The draft plate is provided at its upper and lower ends with heads 80 having reduced portions or shanks 31. The keyhole slots 21 are of such dimei'ls'ions as to permit the draft member to pass through the wide portions thereof, after which by moving said draft member in a forward direction, the shanks 31 will engage the narrow portions of the keyhole slots, thereby retaining the draft plate securely in position and at the same time engaging the pins 26 with the apertures 27. When the parts are assembled, as seen in Fig. 1, the draft link will be held securely in one of the recesses 28 by engagement with the front end of the plow beam; the draft link will prevent displacement in a rearward direction of the draft plate; and the draft plate will lock the top and bottom members 15 and 16 together against spreading movement by engagement of the pins 26 with the apertures 27.

As will be seen from the foregoing description, taken in connection with the draw ings hereto annexed, I have produced a clevis of simple and improved construction which may be readily and quickly applied to a plow beam. By detaching the forward fastening member or bolt 22, the clevis may be swung to one side of the beam, and the draft plate may now be slid back in the keyhole slots 21 and removed, after which the forward ends of the top and bottom members may be moved apart for the removal or replacement of the draft link. The latter may thus be readily adjusted from one to another of the recesses 28. The proper adjustment having been made, the parts are reassembled as before, and the device is ready for use. The construction, as will be seen, is extremely simple, and it has been proven to be thoroughly eflicient for the purposes for which it is provided.

Having thus described the invention, what is claimed as new, is:

1. A device of the class described comprising substantially L-shaped top and bottom members combining to form a U-shaped body and having front arms provided with apertures and with overlapping tongues, said top and bottom members being provided near their rear ends with apertures and near their front ends with keyhole slots, fastening members engaging said apertures and keyhole slots, and a draft plate engaging the keyhole slots and having forwardly extending pins engaging the apertures in the front arms of the top and bottom members.

2. The combination with a plow beam, of a clevis comprising top and bottom members having front arms provided with apertures and with overlapping lugs, said top and bottom members being also provided with apertures near their rear ends and with keyhole slots near their front ends, fastening members extending through the plow beam and engaging said apertures and keyhole slots, and a draft plate provided with recesses in the rear side thereof and with forwardly extending pins engaging the apertures in the arms of the top and bottom members, said draft plate being also provided at the upper and lower ends thereof with heads engaging the top and bottom members and having reduced portions forming shanks that engage the narrow portion of the keyhole slots; and a draft link engaging one of the recesses in the draft plate and retained therein by engagement with the forward end of the plow beam when the parts are assembled.

In testimony whereof I aiiix my signature in presence of two witnesses.
